Covid mask "EASY" version (upgraded to vacc.cleaner Hepa filter)

grabcad

Hi, I've upgraded the face mask design using a modified existing model. The HEPA filter I'm recommending is a great addition - it's available on my link and costs only $7 USD at CZ. This high-quality filter boasts an impressive 25 nanometer resistance, making it more than sufficient for our needs! To use this enhanced face mask, you'll need to source two additional components: a rubber seal with an 8mm diameter to secure the edge of the mask to your face, and rubber straps to attach the entire mask to your head. I've also included STL files optimized for 3D printing in my upload. The filter housing must be glued to the front of the mask. To ensure cleanliness, plan on desinfecting the filter after each use with a UV-C lamp or ozone air cleaner - these devices are commonly used in home infra-sauna setups. I'll also soon release a PROFI version featuring reverse vents to keep the filter dry, ideal for medical and dental applications. After thorough testing, this design has been proven to work 100% effectively!
